Preparation of Al(OH)3 by ion membrane electrolysis and precipitation of sodium aluminate solution with seeds LI Yuan-gao(李元高)1, 2, CHEN Qi-yuan(陈启元)2, WANG Song-sen(王松森)2, YIN Zhou-lan(尹周澜)2...; Abstract: The preparation of Al(OH)3 by the ion exchange membrane electrolysis followed by the precipitation of sodium aluminate solution with seeds......
. Extraction isotherm was obtained with 2.16 mol/L TBP for a typical solution containing 0.1 mol/L of bismuth and 1.0 mol/L of hydrochloric acid. About 98.5 % of bismuth has been extracted from the leaching solution under the optimum condition. Moreover, oxalate was explored as a precipitation stripping agent for BiCl3·xTBP (x=2 or 3) complexes, by which Bi(III) was stripped in the form of Bi2(C2O4)3......

School of Metallurgy, Northeastern University摘 要:solution and low-pH solution, displaying that F- and low pH had much strong aggressive attack to cp-Ti and Ti–3Cu alloy.The corroded surface morphology......
Microstructure and Corrosive Property of Ni-P/nano-CeO2 Coating Electrolessly Prepared in Acidic Condition靳惠明11. College of Mechanical Engineering, Yangzhou University摘 要:Electroless Ni-P/nano-CeO2 composite coating was prepared in acidic condition, and its microstructure and corrosive property were compared with its CeO2-free counterpart. Scanning......
id="ChDivSummary" name="ChDivSummary">The existing form of molybdenum in acidic sulfate solution was studied by means of ion exchange,infrared(IR) spectra and X-ray photoelectron spectroscopy(XPS).The results indicate that the anionic molybdenum species are predominant in acidic sulfate solution,and Mo(VI) can combine with sulfate radical to form heteropoly acid anions[Mo2O5(SO4)2]2- and[MoO2......
solution produced in leaching process dissolves valuable molybdenum and other non- valuable metals [9-11]. So far, many methods have been developed for the extraction of molybdenum from acidic solution, such as chemical precipitation [12], solvent extraction [13-16] and ion exchange [17-21]. Precipitating molybdenum from acidic solution requires a large amount of alkali to neutralize the acid......
